Use :
1. Make measurement of colour and colour difference reflected by materials.
2. Make measurement of ISO brightness (Blue Whiteness R457)and degree of whiteness for Fluorescent whitener.
3. Make measurement of CIE whiteness (Ganz whiteness W10 and Colour cast value Tw10) Make measurement of whiteness of building materials and non-metallic
minerals.
4. Make measurement of Hunter system Lab and Hunter (Lab) whiteness reflectance factor.
5. Make measurement of yellowness.
6. Make measurement of opacity, transparency, light scattering coefficient and light absorbing coefficient.
7. Make measurement of ink absorption.
Technical Parameter:
1. Simulate D65 illuminator to illuminate. Adopt CIE 1964 supplementary standard colorimetric system and CIE 1976(L*a*b) colour space and colour difference formula.
